Scanning NV magnetometry of focused-electron-beam-deposited cobalt nanomagnets
Liza Žaper, Peter Rickhaus, Marcus Wyss +3
Focused-electron-beam-induced deposition is a promising technique for patterning nanomagnets for spin qubit control in a single step. We fabricate cobalt nanomagnets in such a proc…
Magnetic, thermal, and topographic imaging with a nanometer-scale SQUID-on-cantilever scanning probe
M. Wyss, K. Bagani, D. Jetter +7
Scanning superconducting quantum interference device (SQUID) microscopy is a magnetic imaging technique combining high-field sensitivity with nanometer-scale spatial resolution. St…
Magnetic anisotropy of individual maghemite mesocrystals
B. Gross, S. Philipp, E. Josten +4
Interest in creating magnetic metamaterials has led to methods for growing superstructures of magnetic nanoparticles. Mesoscopic crystals of maghemite () n…
Stability of Néel-type skyrmion lattice against oblique magnetic fields in GaVS and GaVSe
B. Gross, S. Philipp, K. Geirhos +5
The orientation of Néel-type skyrmions in the lacunar spinels GaVS and GaVSe is tied to the polar axes of their underlying crystal structure through the Dzyaloshins…
Macroscopic Manifestation of Domain-wall Magnetism and Magnetoelectric Effect in a Néel-type Skyrmion Host
K. Geirhos, B. Gross, B. G. Szigeti +12
We report a magnetic state in GaVSe which emerges exclusively in samples with mesoscale polar domains and not in polar mono-domain crystals. Its onset is accompanied with a…
Nanowire magnetic force sensors fabricated by focused electron beam induced deposition
H. Mattiat, N. Rossi, B. Gross +6
We demonstrate the use of individual magnetic nanowires (NWs), grown by focused electron beam induced deposition (FEBID), as scanning magnetic force sensors. Measurements of their…
Magnetic force sensing using a self-assembled nanowire
N. Rossi, B. Gross, F. Dirnberger +2
We present a scanning magnetic force sensor based on an individual magnet-tipped GaAs nanowire (NW) grown by molecular beam epitaxy. Its magnetic tip consists of a final segment of…
Observation of vortex-nucleated magnetization reversal in individual ferromagnetic nanotubes
A. Mehlin, B. Gross, M. Wyss +6
The reversal of a uniform axial magnetization in a ferromagnetic nanotube (FNT) has been predicted to nucleate and propagate through vortex domains forming at the ends. In dynamic…
Imaging magnetic vortex configurations in ferromagnetic nanotubes
M. Wyss, A. Mehlin, B. Gross +9
We image the remnant magnetization configurations of CoFeB and permalloy nanotubes (NTs) using x-ray magnetic circular dichroism photo-emission electron microscopy. The images prov…
Dynamic cantilever magnetometry of individual CoFeB nanotubes
B. Gross, D. P. Weber, D. Rüffer +5
We investigate single CoFeB nanotubes with hexagonal cross-section using dynamic cantilever magnetometry (DCM). We develop both an analytical model based on the Stoner-Wohlfarth ap…
Thermal and electromagnetic properties of BiSrCaCuO intrinsic Josephson junction stacks studied via one-dimensional coupled sine-Gordon equations
